It was created based on the theme of "A day in the life of the sun," rising in the east and setting in the west. The symmetrical design of the piece focuses on the "world of duality," explaining the truth of all things as two sides of the same coin, such as east and west, morning and night, and light and darkness. The wheel is a story that combines the story of the sun with the "circle of life"1, "east, west, north, south" in various ways, as all things in nature live in harmony with each other in a "ring."
